Abstract (en)
An object of the present invention is to provide a base-releasing composition which suppresses release of a basic compound at room temperature and rapidly releases the basic compound under predetermined conditions, and a curable resin composition using the same.The base-releasing composition of the present invention comprises (A) a specific side-chain crystalline (meth)acrylate copolymer and (B) a basic compound, wherein the amount of basic groups in the (B) basic compound is within a specific range and at least a portion of the Component (B) is included in the Component (A). The curable resin composition of the present invention comprises a specific 2-methylene-1,3-dicarbonyl compound in combination with the base-releasing composition described above.
